I narrowed this down a bit, it crashes with 20020908, but does not
crash with 20020907, so some commit on september 7 or 8 (I don't know
when the CVS tarballs are made) must have broken it.

> - MPlayer crashed by 'Illegal Instruction'. It usually happens when you run it on different CPU than it was compiled/optimized for. Verify this!
> - MPlayer crashed by bad usage of CPU/FPU/RAM. Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and disassembly. For details, see DOCS/bugreports.html section 5.b.
> - MPlayer crashed. This shouldn't happen. It can be a bug in the MPlayer code _or_ in your drivers _or_ in your gcc version. If you think it's MPlayer's fault, please read DOCS/bugreports.html and follow instructions there. We can't and won't help unless you provide these informations when reporting a possible bug.
